Considering the numbered parts of the drawing., the main frame l comprises side and end frame members and suitable cross pieces such as are neeessary to support the various parts of the machine. The frame is provided with suitable legs 2. A power shaft: 3 is journaled in the frame and carries a driving pulley 4. A. drive shaft 5 is journaled in the frame. parallel to and slightly in the rear of the power shaft 3. A fear f3 on the power shaft 3 meshes With the gear 7 fixed on he sleeve l0 Carried by the drive shaft 5. The gear G is considerably smaller llmn the gear I so that the drive shaft 5 turns more slowly than the power shaft il. When operating on different sizes of eartons, il; is desirable to vary the speed ol the drive .shaft 5, and for this purpose I provide an extra sety of gears 8 and 9, the

geur' bein fixed on the power shaft 3 end the gear 9 lxedon the sleeve 10. In order `to facilitate the change from one speed to the other, the ears 7 and 9 are fixed on sleeve 10 Which' 1s slidable on the drive shaft 5 and may be Secured thereto by :i set .ferent By this means a quick shift een be med-e from one driving speed to the other by te using the gears 8 and E) lo mesh. instead of the gears 6 and 7. It is desirable to provide this extra'set of gears on the respectivo shaft because after the machine is once asseni del, it would be practically impossible to vhs nge gears Without dismantling the marfllim. A sprocket 11 is fixed on e clutch member 11:3 which is loosely mounted on the dri i e slml: 5.` lClutch member 123 on the drive shell i is non-rotatable thereon nnd'driven thereby.

kAl rock shaft 14 and handle 15 serve to throw the clutch members l2 amil 1i. into andoutof engagement with each thor un that Arocket 11 may be driven by the drive Sha, t 5. The sprocket 11 is oom'mzted by n chain 16 to a sprocket 17 fixed on e shaft 18'journziled in the frame at the roar end of the mechine.V Sprocket 19 is fixed on shaft 1P 'and connected by chain 2G with sprocket 21 ixedon the cam shaft so that this cem shaft and the cams carried therebyhre 4driven from the shaft 1S.

'.lbe lippe reach of the belt f :ini entries@ roller- 71 i f rides over the upper support 73 while the lower reach extends over the lower support, 7l both of said supports being carried by the frame work. Guide nays 77, 77 are carried by the supports 73 and 74 and engage the sides of the carton at each side of the belt t0 to guido it as it. is carried along by said iced belt.

A rock shaft 7S is journaled in the upper ends oit' the stalulards G0 and carries a stop 79 dependingr between the supports 05, 05 in position to hc engaged by the .articles to be wrapped as they are earried along hy the article feed belt. The engagement of said articles with the stop tendsl to rock shaft 7S which carries arms 80 and Si.. An arm S2 is secured to one of the standards 60 and hasl a laterally bent, end to which is secured one end of the spring S3, the other end of which is secured to the arm S0 at Si. This spring tends to hold the rock shaft nm'mallv with the `top 79 in a vertical position. as :shown in Fig. XIII. The arm 81 on the rock sha ft 78 is coniuaetml by link ei with an arm Sti on rock shaft S7 which extends longitudinally of the machine. This rock shaft serves to actuate the clutch mechanism for the paper feed drive.

A reciprocating bar 88 is mounted longitudinally of the frame of the machine and guided on suitable Ways 89. The forward end of said reciprocating bar is provided with a vertically extending portion 90 to which is secured a pusher member 91 having a portion 92 bent at right angles to the body of the pusher member and extendingr in a plane at right angles to the article feed belt as shown 'i Fig. XVIII. The bar SS is reeiprocated by means of the arms 93 and 93 fixed on rock shaft 94, arm 93 being connected to the bar 88 hy the linlr 95. The arm 915' is connected to and ali'tuated by the liul 9G, connected at its forward end to the arm 97 on the rock shaft 9H, said rock shaft 9B beingr journaled in the vframe and having an arm 99 with a roller 100 engaging in cam way 101 of cam 102 which is fixed on the cam shaft 22- journaled in the frame as .has been heretofore described. By this means, as the cam shaft 22 revolves, the bar 8S will be rcciproeated to carry the pusher member 91 back and forth across the article feed belt and above the same. the relation of the parts appearing in Fig. XVIII.

A trip member 103 is secured to the portion 92 of the pusher member 91, said trip member being disposed to engage the end of the lever 104, which is pivoted on the standard 105, as the pusher member moves to its inner position with the, portion 92 extending across the article feed belt. Lever 104 has a dog 106 pvoted in the other end thereof and provided with a springr 107 normally tending to throw the outer end ot the .flog 106 above the plane of the lever 101 so as to engage the end of the arm 80 on the rock shaft 78. A springr 108 is connected at: one end to an arm 109 extending from the standard 105 and at the other end to a pin 11.0 carried by the lever 104, said springr 108 tending to hold the. lever 104 in sucli position that the dog 106 will engage the end of the arm 80 to prevent. the rocking of shaft 78. As the pusher 91 is reciprocated, the trip member 103 engages the end of the lever 104, rocks the lever 104 on its pivot and carries the dog 106 from in frontJ of the arm 80 so as to permit the shaft 78 to be rocked by the carton pushing against the stop 79. This causes the reciproeation dof the link S5 and the consequent actuation of the rock shaft 87 which operates the paper feed clutch mechanism.

Bars 111 and 112 are secured to the vertial portion 90 of the bar 88 and to the pusher member 91 by means of the bolts 113, said bars being spaced apart by the spacing blocks 111. Pins 115 are slidably mounted in said hars 111 and .112, said pins having rounded heads 11G extending slightly bev yond the front surface o1' the pusher menr ber 91. Each of said pins has a shoulder 117 and a spring 118 engages the rear bar 112 and the shoulder 117 to yieldingly hold the pins with their heads projecting beyond the front surface of the pusher 91. When the pusher member engages a carton, the springnT pressed pins 115 yield slightly so that. the carton is yieldingl held in position by the pusher member. standard 119 is secured to the 'frame by the bolts 120 and extends vertically upward in such a position that, as a carton is delivered by the carton feed belt in front of the pusher niember 91, upon reciprocation of the bar 88, the pusher member 91 shoves the carton lair-rally against and holds it in engagement with the standard 119 until such time as it shall be forced downward upon the sheet; of paper in which it is to be Wrapped.

I will now describe the paper feed and cutting?r meclianism and the sheet delivery mechanism, by means of which a. sheet of paper of the required size is eut from the web of paper and delivered to a position beneath the carton so that the carton may be forced down upon it. A roll of paper 122 is carried by arms 121 secured to the side of the frame. The paper feed rolls are journaled in brackets 123 secured to the side of the frame. Shafts 121 and 125 are journaled in the outer ends of said brackets 123, the upper shaft 125 being movable vertically in its bearing. These shafts carry the feed rolls 120 and 127 respectively, between which the web of paper 128 passes. The roll 127 is held yieldingly against- 1'oll 126 by the springs 123 connected at their lower ends to arms 121. .Inst in front of the roll 127 is journaled au idler roll 129 over which the istY The shalt 130 is journeled in the hr1/zekere 125 nel carries the cutter roll 13: heving tho knife .lll which eonots with the roll 134 en the shaft lill to eut the peper.' inte .eheetei t pi-(iper eine.

This gen1' meshee with the gen1' 158 which i5 connected to the lieve] gear 159, the latter meshing with the bevel geur 111() on the end ol' Shaft 131. Shaft 131. carries e gear meehing` with the gear 161 on Shaft 130. On the other end of shaft 131 fixed geur 162 which meshes with :i gear 16?) adjuetnhly joui-nailed in e link 164 pivoted on the hrnoket 123. The gear 163 meshes: with gear 165 fixed on the end of shaft 1&24. On. the other end of the shaft 124 is fixed :i gear 1G13 meshing with :i gear 167 on Shaft 125. It will thus he seen that all of the paper ,feed rolls and the peper cutting rolls ere driven from the gear 137 und that the letter gear rotatesl during but part of the revolution of the earn shaft because of the eluteh mechanism which is controlled by cam 146 on the rain shaft, and hy the end of the hell ef-ltnk lever 15E! which is aetnetedhy the rnelt Shaft R7 controlled by the erin 81 on the wel' shaft 73 which carries the Stop 79. It will ihm he eeen that when thc'enrtone are heilig .ted regularly through the mee chine so that the stop 79 is turned out el" the vertical, the erm of the bell crank lever 152 will be lowered so that at each revolu tion of the eem 146, the raised part thereof will aotuate the link 150 to cause it to engege the tail 155 of the bell crank 153 to allow the clutch members to spring into engagement so that the gear 137 will he driven by the cam shaft 22. It will therefore be epparent that the paper feed mechanism will be driven during e part of the revolution of the cani shaft und that it will. not he driven at all unless cartons are being fed into the machine.

The` rod '.168 is carried by the brackets 23 find e. guard easing 16? for the paper cut und the sheet of puperis delivered from thf.`

,paper Cutter upon the peper feed ways the edges of the sheet being guided oy eaid fingers 170. A shaft 171 is jonrnuled in the tranne end carries u, pair of rollers 172 whieh engage Ythe bottom of the sheet of )inneres it is delivered from the peper eutter. A shaft 174 is jonrnnled in the frame alloro seid Shaft 171 and carries a pair 0f rollers 176 eoi'perating with the rollers 17:31y

:ind e spur gear 175 meshing with the spur geur 173 on the end of shaft 171, so that shafts 171 and 174 are driven in opposite directions, the sheets 0f peper being delivered from the paper cutter between the r0llers 172 and 176. Shaft 47 is jonrnnled in the freine and driven by the gear 46. This r@huilt carries e plurality of rollers 177 and :l gear 178 meshing with a gear 179 journaled on the pin 180 carried leyY the frame.

A shaft 18]. is journaled in the frame parallel to the shaft 47 and carries a plurality of rollers 182 and a gear 183 meshing with the gear 179. The shaft 181 also carries the sprocket 184 connected by chain 185 with sprocket 186 on the shaft 171. A spur gear 187 is fixed on shaft 181 and meshes with a spur gear 188 jolirnaled on the frame and meshing with a gear 190 carried by the stub shaft 189 which has fixed thereon a roller 1,91. A second stub shaft 192 is journaled in the frame parallel to lshaft 189 and earries a roller 193 and a sprocket 190 connected by chain 195 with the sprocket 194- on shaft 189, said shaft 192 also carries a gear 207. A gear 197 is journaled on the frame and meshes with the gear 183. A stub shaft 199 is journaled in line with shaft 189, said shaft being provided with a spur gear 1.98 meshing with the gear 197 and carrying a roller 2700. and a sprocket 201 connected by chain 202 with sprocket 203 on the stub shaft 204 which is parallel to the shaft 199 and in line with the shaft 192. The shaft 204 carries a roller 205 and a spur gear 200. Power is delivered to the whole system of shafting on which these lower rollers are carried by means of the shaft 47 driven by the gear 46. It will be seen that all of the shafts are driven in the same direction and all of these rollers engage the bottom of the sheet of paper to carry it into position beneath the carton.

A pair of link members 208 are journaled on the rod 135 and are pivotally connected to members 209. The shaft 210 extends through member 209 and 208 connecting them together, appears in Fig. I. The shaft 210 carries a gear 212 and a pair of rollers 211 cooperating with the outer rollers 177 on shaft 27. Gear 212 meshes with the gear 178 so that the shafts 210 and 47 are driven in opposite directions. In the other end of each member 209 is journaled a shaft 213 carrying gears 214 and a roller 215, one of said gears 214 meshing with the gear 183 on shaft 181 and the other gear meshing with the gear 187 on shaft 181. The rollers 215 ooperate 'with the eorrespo'nding rollers 182. Each member 209 is connected by links 216 to the shaft 218 extending through the link member 21,7. Shafts 218 carry gears 219 and rollers 220. The rollers 220 cooperate with the corresponding rollers 191 and 200 and the gears 219 mesh with the gears 190 and 19S respectively. In the outer ends of members 217 are jonrnaled shafts 221 on each of which is xed 'a roller 223 and a gear 222 coperating with the rollers 193 and 205 and the gears 206 and 207 respectively. It will be seen that I have provided a set of feed rollers engaging the bottom of the sheet and a corresponding set of feed rollers engaging the top of the sheet, the latter rollers being driven in the opposite -lireetion from the bottom rollers 1nd being earried by a linked snpi'iorting structure by means of which the top rolls can be easily removed in case access lo the bottoni rollers is desired.

A stop member 224. is secured to the frame and is provided with a vertical portion depending across the top of the feed belt 49 in a plane at right angles thereto and forming a stop to limit the movement of the carton carried by said carton feed belt. A slide member is slidably mounted upon the standard 119 and carries at its lower end a plunger 226 which engages the top of the carton, held by the pusher 91 against.- the standard 119, so as to force lsaid carton down upon the wrapping paper and to force the carton and vvrap ping paper down upon the Wrapping oonveyer ways through an opening provided in the paper feed ways. The slide inembe;` 225 is connected by a link 228 to the end of an arm 227 on the rock Shaft 98, said arm being actuated by a cam 229 on the cam shaft 22.

A pair of rock shafts 230 are journaled on the frame, extending transversely thereof a slight distance above the paper feed ways 48 upon which the sheet of paper rests. Each of these rock shafts carries a number of fingers 231 which rest u on the surface of the sheet of paper which has been fed into place upon the. paper feed ways beneath the carton, said fingers resting upon the paper and serving to hold it under a slight tension so that as the carton is forced downwardly the paper withdraws `gradually from beneath the fingers and is wrapped smoothly around the carton. On each roclr shaft 230 is secured an arm 232 connected by a link-233 with an arm 234 fixed on the rock shaft 235 which is journaled on the frame. Said rock shaft 235 has an arm 236 which extends over and rests upon the top of the plunger 226 so that as said plunger moves upward, toward the limit of its upward movement, the arm 230 will be lifted, rocking the shaft 235 and rock shaft 230. and lifting the fingers 231 11o-permit a new sheet of paper to be fed into place upon the Ways beneath the fingers 231 so that, when the plunger starts to descend to force a carton downward, the fingers will descend and rest upon the paper holding it under slight tension. A stop 237 is secured to the frame in suoli position as to limit the downward movement of the fingers 236 as will appear from Fig. XVIII:

Arms 238 are fixed on the shaft 239 which is journaled on the under side of paper feed ways 48 and carries a small gear 239 meshing with the gear 240 which is journaled in hangers carried by the frame
